The next NDK to take these headers only supports API 21 and later, so
clean up some of the trivial cruft.
This doesn't include the remaining "legacy inlines", since they're a bit
more complicated. I'll remove those in later changes.

API level 19 is no longer supported by the NDK.
While I'm here, let's remove the duplicated structure defintion (as
we've already done for `struct stat`).

These cause great confusion, so explicitly point out that apps can't use
one, and probably want the other.

Although the NDK ABI for x86 doesn't include SSE4.1, it's needed for
roundss/roundsd, and we've used that (via hand-written assembler) in the
x86 libm since Android M. We've recently switched to using compiler
builtins to generate the assembler instead, and without allowing the
compiler to use SSE4.1, it can't (resulting in infinite recursion as
these functions defer to themselves for an answer).
Given that the x86 libm.so has required SSE4.1 for 8 years at this
point without anyone noticing, let alone caring, let's just retain the
status quo rather.
(Despite the fact that this caused boot failures for cf_x86, I didn't
notice when testing the 32-bit libm.so from a cf_x86_64 build because our
x86-64 ABI *does* include SSE4.1, and the BoardConfig.mk for cf_x86_64
explicitly chooses "silvermont" as the 32-bit cpu variant, implicitly
enabling SSE4.1.)

armv8 arm32 has a single instruction for the floor() family, but armv7
arm32 doesn't. Play stupid preprocessor and namespace tricks to get
the best of both worlds (using __ARM_ARCH in code is less awkward than
trying to do similar with armv7_a and armv7_a_neon in the build system).

The gwp_asan_integration.malloc_tests_under_torture test fails
when trying to run the malloc.zeroed* tests. So skip these
tests in that config.

It looks like the only functions current clang can't do are the lrint
family. Everything else looks good, and the fact that clang has builtins
means we shouldn't normally see calls to any of these functions anyway.
